To all whom it may concern:

Be it known that I, OSCAR A. BUsE, a citizen oi the Republic 'of Peru,and a resident of Lima, Peru, have the following is a full, clear, andexact description.

This invention relates to improvements in tobacco pipes, an object beingto provide a pipe made oi separable sections so that it may be readilytaken apart for cleaning.

Another object is to so construct the stem of the pipe that saliva willnot enter and mingle with the smoke and tobacco.

Another object is to provide means for cleaning the smoke of nicotin orthe like before it enters the smokers mouth.

Other objects of the invention will appear in the general description.

I will describe a tobacco pipe embodying my invention, and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters o reference indicatecorresponding parts in all the igures. Figure 1 is a side elevation of atobacco pipe embodying my invention; Fig. 2 is a longitudinal sectionthereof; Figs. 3, 4, 5, 6 and 7 are sections respectively on the lines3-3, 4 4, 5-5, 6-6 and 7-7 oi Fig. 2; Fig. 8 is a fragmentary viewshowing a modified form of joint for the stem sections; Fig. 9 is asectional view of a bent mouth piece; and Fig. 10 is a sectional detailshowing a means to prevent possible loss of a plug or closure employed;and Figs. 11, 12, 13 and 14 show modifications in the smoke duct.

It may be here stated that the pipe may bemade oi brier, or othersuitable wood.

Referring to the drawings, 10 designates the bowl of the pipe, the stemof which consists of a lower section 11 which is formed integral withthe bowl, and a detachable upper section 12. These sections 11, 12 meetor engage together at about the center at the sides. The end ofthe stemsection 12 adjacent to the bowl is inclined or beveled as indicated at13 to engage against the under-cut wall 14 made in the pipe bowl, thusproviding a lock at said end of the stem. The outer ends oi the stemsections are screw threaded to engage with the interior threads of aferrule 15, and also engaging with the thread is the mouth piece 16.When the stem parts are assembled, a plug 17 of suitable material isengaged partly in the stem sections and partly in the mouth piece, andto insure the proper alinement of the mouth piece, or the plug therein,the plug at its upper side is provided with a slight projection 18 thatmay be sions formed in the adjacent ends of the stem section 12 and themouth piece 16. At one end, the stem sec- UNITED STATES PATENT ossron.

tion 12 is provided with a short metal tube 19, which providescommunication between the pipe bowl and a chamber 20 in said stemsection, At the other end of the stem section 12 is a short tube 2l,providing communication between the said chamber 20 and a metal tube 22extended through the plug 17. This tube 22 is arranged at a downwardincline and is projected into a chamber 23 formed in the mouth piece sothat saliva that may pass through with the smoke will flow into' saidchamber 23, and pass outV into the saliva and nicotin chamber as will behereinafter described.

To clean the smoke of the greater portion, if not all of the nicotin, Iplace in the chamber 20, packings 24, 25, of absorbent cotton, or othersuitable material, and these devices 24, 25, are held yieldingly inplace, or with suiicient pressure by a coiled spring 26 in said chamber20.

The lower portion or" the upper stem section 12 is normally closed bymeans of a plate 27 of any suitable Vmaterial, which has bevel edges forsliding in channels formed in the stem section 12, and the outer end ofthe plate 27 is extended to engage in a notch 28 formed in the endoi theplug 17 Below the smoke tube 22 the plug 17 is provided with a passage29, which provides communication between the lower portion of thechamber 23 and a tube 307 which passes through a partition block 31, andorms one end wall of a saliva and nicotin receiving chamber 32, theother wall being ormed by a partition block 33, through which a tube 34passes into a saliva and nicotin receiving chamber 35. It willbe seenthat the tube 34 is arranged on a lower plane than the tube 30, andtherefore, it will be practically impossible for saliva, nicotin or thelike, to ow back from the chamber 35 into the chamber 23, and thence tothe mouth piece. In other words, the said tubes 30 and 34 orm a trap.The upper side o the lower section 11 oi the stem is closed by a slideplate 36, which also has its end projected to engage in the notch 28.The opposite or forward end of said slide plate is also extended toengage in a slot 37 formed in the pipe bowl.

To prevent any possible leakage or passage of air over the partitionblocks, cushions 38 of rubber, or other suitable material are seated inslots formed in the upper straight sides of the said blocks and designedto engage against the under side of the slide plate 36. To

By such arrangement, more room will be provided below the tub es. Belowthe saliva chamber 35, the stem section 11 has an opening, and aroundthe opening is a downwardly extended ange 39, having an interior threador engaging the exteriorthread of a metal cap or smoke tube or ductleading to the part 17 is extended `5l having a compound channel 55provided with an cup 40, and seated in the upper portion oi the openingis a disk 41, of suitable material, having a short tube 42, whichprojects into the cup 40, and through which saliva and the like isdesigned to pass into said cup. This projecting tube 42 forms a trap toprevent saliva from flowing out of the cup when the pipe is in anyposition, that is, straight up, as in a persons pocket, or lying on theside.

If the connection is not deemed sufficiently tight between theconnecting sides of the stem sections, I may provide a joint, as shownin Fig. 8, which consists of a strip 43 oi aluminium or other suitablemetal, seated and locked in a channel formed in one of the stem sectionsand adapted to engage -in a channel formed in the other section.

When my invention is used in connection with a curved mouth piece 44,the projected portion of the into a recess 45, the lower wall of whichis extended downward underneath said projection, as indicated at 46,thus preventing the passing ot saliva back into the smoke duct.

It will be obvious that a pipe embodying my invention is hygienic as thesmoke will be practically cleaned before passing into the smokers mouth,and further, ther pipe may be readily taken apart for cleaning.

Io prevent the cap 40 from being wholly detached, I connect to it a wire47, which passes through the tube 42 and at its upper end is providedwith a cross-head 'for engaging with the upper end of said tube.

Instad of the spring and packing before described, I may place in thechamber 2O a smoke-passage block, consisting of a lower member 48 havinga compound channel 49 provided with an inlet 50;` a top member outlet52, and an intermediate plate 53 provided with an opening 54.

Having thus described my invention, I claim-as new y and desire tosecure by Letters Patent,-
